Threads:
  - A process can run the program parrallely executing various instructions parallely

depends_on : 
  - db   # This makes the service to restart on the service that its depending on restarts. But not vice-versa
restart: always  # This tells the service to restart when a fault occurs

## some commands
$ docker network ls
$ docker network inspect <network_name>
$ docker-compose exec <service_name> sh 
$ docker-compose scale <service_name>=3  # here 3 is the desired count

Lamda

More like an annonymous function

even_num = lambda x: x%2 == 0

Map

Takes a functions/lambda and an iterable, and returns a map object. So convert to list

square = map(lambda x: x*2, [1,2,3,4,5,6]) #[2, 4, 6, 8, 10, 12]

1. Obtain the root cert from: https://s3.amazonaws.com/rds-downloads/rds-combined-ca-bundle.pem . This cert will be used for connecting to the db instance when SSL is enforced

Create the new parameter group:

2. Create a new parameter grp based on the DB engine version, as all the db instances are in default parameter grp [Default parameter grps cannot be modified]
3. Change the rds.force_ssl to 1 from 0
